Engine question

I believe I’ve decided to swap in a sr20ve into my nx2000, What I’d like to know is where would be a good place to buy the engine (I had emailed autodream to see if they could get one but no answer)…and also a shop that could do the install, unless I can get some people to help me out, but I’ll deal with that later.

Also would like to know what are a few good exhaust systems and the costs…probably gonna going with a 3 inch

call autodream if you want an answer quick,they are busy people.
